FIELD: physics.
SUBSTANCE: proposed device comprises housing with opening to receive reflector with light source. Reflector front tail outer perimeter height is smaller than reflector opening outer perimetre height. Note here that reflector front tail outer perimetre height is in fact equal to reflector opening inner perimetre height. Reflector cross section shape decreases to direction of its insertion.
EFFECT: ruling out friction between housing and reflector, reduced brightness.
